MapAPI module is a helper module for the upcoming Map module. By itself, MapAPI doesn't do anything.
The motivation behind this module was to create a game that is powered by Drupal core. The first step in our work is to release flexible API that can allow us to build that game; MapAPI is part of it.
MapAPI allows you to create game maps based on coordinates. each map can contain arbitrary number of tiles and each tile can contain any number of content items.
MapAPI was designed to be very extendable by new modules that will be introduces for the game. New modules can introduce any new serialized content array indexes to be stored in the content table. the type of information stored in the table is non-important for the MapAPI, the important part is that it can store ANY information and pass it back to the parent module for processing.
